ABSTRACT:
A word processing system is provided which includes a processing apparatus for processing textual information and for controlling a plurality of controlled units. The processing apparatus further includes a memory apparatus for storing such textual information. The system also includes a first controlled unit comprising a data entry device for entering textual and command information into the processing apparatus and a second controlled unit responsive to the processing apparatus for printing the textual information. The processing apparatus is responsive to the command information to perform editing operations, including insertion and deletion of characters on the textual information, to store in the memory apparatus the edited textual information and information defining the inserted and deleted characters and to select and print either the edited information, the information as originally stored in the memory apparatus or the edited information with the deletions restored. In a preferred embodiment, the edited information with the deletions restored may be printed with additional characters to set off the insertions and deletions so that the inserted and deleted characters may be readily identified by inspection.
